AITA for kicking out house guests that stayed an additional 4 days after I asked them to leave?

My girlfriend of 2 years (33F) and I (30M) live in a cozy 2 bedroom apartment on the river. I love to fish there and so does she, which is how we met. Her brother newly turned 18 has never seen the ocean before, and my girlfriends family lives in the middle of the U.S. (Illinois) so its a big deal for him. She invited her parents (50s), her brother (18) and her sister (29) to come stay with us for a “week” (we were supposed to pick them up on a Friday and drop them off the next Sunday). <br><br>They got here on the Friday and I immediately noticed that her mother and sister had more luggage than seemed necessary for 6 days. I asked and they said they packed extra just in case they needed anything. Ok, no big deal. The first morning they were here my girlfriend and I went through our normal morning routine. I make coffee and she does yoga, then we eat breakfast and I take her to the airport to start her shift as a flight attendant and then I drive to work. <br><br>Her mother made herself at home and helped herself to my juice and my girlfriend asked if I could take her brother and sister to the river instead of taking her to work. I told her it was no problem but I only have one extra car seat so I would have to leave her sister behind. Her mother told me to just take her as well and that she could ride in the front seat. I did so, but that meant that I had to miss work that day because I still had to take my girlfriend to work. They didn’t leave my house that day until 2pm. <br><br>The next morning I woke up to my girlfriend’s sister squeezing my oranges to make juice. I work hard for my money and I don’t like to waste so I save the peels and seeds and juice them a second time to make a secondary batch of juice that may not taste as good but is free and it can be used to make marmalade with. It’s a habit that I have developed over the years and I find it very comforting. I was more shocked than upset and I told her that it was no worry it’s only juice but in the future please don’t throw away the peels. <br><br>I took them to the river again the next day and spent the day fishing with them while my girlfriend was at work. They had never seen the ocean and were amazed by it. I could tell they were shocked at how big it was and impressive. I could tell that my girlfriend made up a story about me because they kept calling me captain Ahab. They told me they were excited to tell their friends back home about me. <br><br>I dropped them off again at 2 and when they got back my girlfriend’s mother asked why I didn’t stock up the fridge. I told her it was because I didn’t know they would be staying so long. I asked if she needed anything and she asked if I could buy some steaks and another gallon of milk. I went to the store and bought the groceries for them and then cooked the steaks for them. They left again at 2 the next day. <br><br>My girlfriend got off work and asked me why I was so quiet. I told her I was confused as to why her family was still at my house. She said they were having a good time and that they haven’t seen the ocean in a long time. I asked her if they were planning on staying longer than she originally said. She said they told her they were having a good time and they asked if they could stay longer and she told them it was fine. I told her that she needs to ask me before inviting people into my home and that they need to leave by Sunday or else I will kick them out. <br><br>The next morning her sister and mother tried to use the washer and dryer but loaded it wrong and broke the washer and dryer. I told them it was okay and fixed it. My girlfriend asked what was wrong and I told her and she told me not to be petty. When I dropped them off that day I told her family that they need to be out by Sunday. They agreed that they would be gone by then. <br><br>Sunday rolls around and they aren’t packing their things so I asked them when they are planning on leaving. They said they hadn’t intended on leaving until the following Sunday. I told them that they cannot stay that long and asked if they were squatters. They told me they can’t control their schedule. I told them they are free to go at anytime and I will take them to the airport whenever, or I can drop them off at a hotel. <br><br>Her sister said that I was being rude and I told her that I didn’t invite them and that my girlfriend didn’t ask me before allowing them to stay longer. I told them if they aren’t out by 6 they will be trespassing. They told my girlfriend what I had told them and she told them that I was being a jerk. She asked if we could talk in private and I told her we could talk there in front of everybody and she told me to show some respect in front of her family. I told her that it was my house and they had overstayed their welcome and that if she couldn’t get them out by 6 then I would. <br><br>This argument got very heated and she told me that I was being selfish and that I didn’t care about her or her family. I told her that her family had no right to be in my house and that they broke my washer and dryer and skipped work for me and wasted my groceries. She said I was being petty and that it wasn’t a big deal. <br><br>At 6 I grabbed their bags and put them in my girlfriends car and told them I would drive them to a hotel and pay for their stay until it was time to take them to the airport. Her girlfriend called me an asshole and told me that I was ruining our relationship. I told her that our relationship is over and I can’t take her disrespecting me like that. I took them to a hotel and paid for 5 nights and gave them $500 to get food and then went back home and changed my locks. She won’t answer my calls or texts and is telling people that I “kicked her family out” and that I’m an asshole.<br><br>AITA?
